I write a value to a specific location, read it back IMMEDIATELY, and it's changed! There's NO WAY any other part of my program can be involved in that. Obviously wasn't the case here, and one would have to be quite forgetful (I could manage it!) but you could (I think?) also see this behaviour wit...

Are you describing Mrs Roland as an "ancient artifact"???



Big trouble ahead

I've told the seller they're talking nonsense.

Maybe it didn't "leak" but "oozed slightly"

+1 for Mark at RetroClinic.

This might be because the character is re-defined - so the $ will look a bit different.

Sorry, can't answer the "what next" question but think this is why you are seeing the 1/4 circle.

Well, I sort of see what you mean, but on the other hand it is an auction. Whether he is selling a broken thing for 10p or £100 doesn't really matter - he's being open about that he doesn't know what state it is in and he's offering it for sale at the buyer's risk. It's up to the buyer to figure out...

Might be my memory playing tricks but wasn't there a DFS (or maybe emulator?) issue where it didn't realise you had changed the disc? So although you've told the emulator to use the new SSD, the emulator or DFS uses the cached catalogue of the original disc (hence the Not Found message - it's lookin...

Not sure the 80s and 90s count as "ancient" but people born after 2000 might disagree! :lol: I collect the books I enjoyed from BITD, including down to the same editions/covers if I can. And obviously vinyl records have made a big comeback, and also cassette tapes - but neither of those in...

I've removed the email address (might save you a bit of spam!) but I can't enable PMs - you have to make a certain number of posts before that is auto-enabled (or ask an admin).

Might be one for @flaxcottage: https://www.flaxcottage.com

Think that sums up retro-computing!

I've had a quick whiz round and looks OK from here.

(Oh, PHP 8.2, eh, fancy! Just starting to migrate my $DAYJOB sites to 8.2 ...)

Welcome, Adrian.

Threw out most of my Acornsoft boxes but went through a collecting phase a few years back and got a few (cough!) replacements.

How about starting with a specific box (if you still need to do this - sounds like a few offers to help out already.)

Welcome! I don't have a physical Beeb at present but would like to rectify that - any options other than ebay? It depends how confident you are at fixing a cheaper but potentially non-working machine. I've got a few machines from Mark at RetroClinic - he does a great job and the machines have reache...

Well-deserved

Very very very clever people and set a lot of us here up in IT.

Same here - turns out there's a bit more work and brain power involved than reading a book as I sadly discovered!

My school had 380Z and 480Zs - had to do my A-Level Computer Studies project on a 380Z instead of using the BBC B micros the school also had (and I was familiar with from home). My code worked and was complete but it hadn't got through to me that a lot of the marks came from the documentation rather...

Welcome!

That's almost exactly the same set of books I had BITD except my Birnbaum (1st edition) had green on the cover.

DFS *COPY definitely takes as much memory as it wants: e.g. http://www.retroisle.com/others/acornbbc/OriginalDocs/Acorn_DiscSystemUG.pdf "Warning This command may overwrite the contents of memory. If you have a program or data in memory that you want to keep, save it before you use this command...

Thanks for all the write-ups - good to see you all out and about again even if there's a bit of bad news at the end of it all - hope you all get well soon!

Very similar to yours, but starting with a decluttering so I can actually have space to DO things.

Mind you, last year's resolutions very similar and not much happened!

But the decluttering has started at least.

Looks like a good haul - hopefully no disc fungus or other decay

Still got my discs from BITD but haven't got around to checking them yet.

Good to see you fellows still going strong, keep it up!

That's what it sounds like to me, too!

That's not going to end well, is it?

I changed RR so that one key bombed & fired at the same time, but still wasn't enough to let me finish the game.

Welcome!

I can't give you the exact instructions, but some pointers. So you'd have to find the *TAPE code that haerfest mentions, and that will be - I think - 9 bytes. So the first LDA will be &A9 in hex. The JSR OSBYTE will be something like &20 &F4 &FF - 3 bytes for that instruction. You wa...

I've been watching with interest and bookmarked for "come and have a proper look one day" - but that's such a long list!

But have been reading your posts and love the colourful graphics.

Summer's coming in and my keyboard melted
